Definitions

  • the invention relates to a bypass ventilation system for electric blowers for cooling engine compartment components in motor vehicles with a cooler, on the side facing away from the direction of travel an air funnel is arranged, in the outlet of which an electric blower with a blower motor and a fan wheel is attached.
  • DE-OS 41 02 645 For cooling engine compartment components such as oil tanks, gears, valve covers or batteries, it is known from DE-OS 41 02 645 to drive a fan by the kinetic energy of the exhaust gases of the internal combustion engine in the manner of an exhaust gas turbocharger. It is also known to extract from the air funnel of so-called pushing fans, i. H.
  • Blowers which are arranged in the direction of travel in front of the radiator, branch off a bypass that is supplied to the cooling engine compartment components.
  • the present invention has the object to provide a cooling system for the engine compartment components an ⁇ admit that can be realized in a simple manner with low overhead 35.
  • This object is achieved in that at least one side wall of the cooler has a bulkhead channel which is open in the direction of travel and which penetrates the air funnel on the lateral surface and ends in the area immediately in front of the fan wheel plane, in such a way that the majority of the outlet cross section of the bulkhead duct is covered by the rotating vanes of the fan wheel and cold bypass air is drawn in by the electric blower and is pressed into the funnel-shaped transition behind the fan wheel plane with an air hose as a continuation for forwarding the bypass air to the engine compartment components.
  • the outlet cross section and the funnel-shaped transition from one another are vertically offset by an offset piece, so that the vectorial superimposition of the bypass air sucked in from the outlet cross section and the bypass air acted upon by the fan impeller gives a resultant which predominantly points into the funnel-shaped transition.
  • a segment-like bulkhead wall is installed in the outlet of the air funnel parallel to the fan wheel plane in the area of the outlet cross section, half of which is at the top and directs warm cooler exhaust air away from the funnel-shaped transition on both sides of the outlet cross section.
  • FIG. 1 is a perspective view of the bypass ventilation system
  • FIG. 2a shows the front view of the bypass ventilation system
  • FIG. 2b shows the top view according to FIG. 2a
  • FIG. 2c shows the side view of FIG. 2a.
  • the direction of travel is marked with reference number 1.
  • the air drawn in is marked 2, which flows through the cooler 4 and passes through the fan wheel 10 as the main air flow 8.
  • On the side of the cooler 4 is the inlet of the bulkhead duct 6, which guides the bypass air 3 and penetrates the air funnel 5 on its outer surface.
  • the electric blower with the blower motor 9 and the fan wheel 10 is mounted in the outlet of the air funnel 5.
  • the bulkhead duct 6 ends in the area immediately in front of the fan wheel level with its outlet cross section 12. Behind the fan wheel level is the funnel-shaped transition 6 ′′ with the air hose 7 as an extension, which directs the cold bypass air 3 to the engine compartment components to be cooled, such as the battery and /or forwards electronic control units for engine management.
  • Funnel-shaped transition 6 'and outlet cross-section 12 of the bulkhead duct 6 are vertically offset from one another by the offset piece 6', so that the vectorial superimposition of sucked-in bypass air 3 from the outlet cross-section 12 and bypass air 3 acted upon by the fan wheel 10 gives a resultant, which mainly points into the funnel-shaped transition 6 * •.
  • the bulkhead 11 In the outlet of the air funnel 5, the bulkhead 11 is installed parallel to the fan wheel plane in the area of the outlet cross section 12, which prevents hot radiator exhaust air from reaching the funnel-shaped transition 6 '.
  • the bulkhead 11 is located in half at the top and bottom on both sides of the outlet cross section 12, as is particularly illustrated in FIG. 2 a.
  • the bulkhead wall 11 is preferably designed as a segment.
